# Configuration file for the Sphinx documentation builder.

# This file does only contain a selection of the most common options. For a

# http://www.sphinx-doc.org/en/master/config

# -- Path setup --------------------------------------------------------------

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.

# -- Project information -----------------------------------------------------

# Single-sourced versioning for docs with inspiration from pip:
# https://github.com/pypa/pip/blob/04d8841ace46d49a1443ef56f1205a70019a1a2f/docs/html/conf.py
version = release = 'dev'

# Readthedocs seems to install pip as an egg (via setup.py install) which
# is somehow resulting in "import pip" picking up an older copy of pip.
# Rather than trying to force RTD to install pip properly, we'll simply
# read the version direct from the __init__.py file. (Yes, this is
# fragile, but it works...)

init_file = os.path.join(docs_dir, '..', 'diffprivlib', '__init__.py')

# -- General configuration ---------------------------------------------------

# If your documentation needs a minimal Sphinx version, state it here.
